Abstract:

This PhD thesis focuses on improving the limit of detection (LOD) of Raman biosensors by using surface enhanced Raman scattering (SERS) and/or hollow core photonic crystal fibers (HC-PCF), in conjunction with statistical methods. Raman spectroscopy is a multivariate phenomenon that requires statistical analysis to identify the relationship between recorded spectra and the property of interest. The objective of this research is to improve the performance of Raman biosensors using SERS techniques and/or HC-PCF, by applying partial least squares (PLS) regression and principal component analysis (

Les structurations de la matière à l'échelle nanométrique ont ouvert de larges champs d'étude. L'analyse des propriétés structurales des nanostructures, de leur degré d'organisation ainsi que leur influence sur les propriétés électroniques représentent actuellement un défi de première importance. Pour accéder à ces informations, il est souvent nécessaire de faire appel à un ensemble de techniques expérimentales et numériques souvent complexes dans leur mise en oeuvre. Dans cette contribution, nous étudions l'organisation et le confinement électronique dans des multiplans de boîtes quantiques,

It describes the theory of resonance Raman scattering, the experimental setup for Raman spectroscopy and a few Raman spectroscopy measurements. The measurements were performed on biological samples oak tree leaf and lactobacillus acidophilus and bifidobacteria from probotioc medicinal capsules.

Abstract:

Raman scattering can accurately identify molecules by their intrinsic vibrational frequencies, but its notoriously weak scattering efficiency for gases presents a major obstacle to its practical application in gas sensing and analysis. This work explores the use of high finesse (50 000) Fabry-Pérot microcavities as a means to enhance Raman scattering from gases. A recently demonstrated laser ablation method, which carves out a micromirror template on fused silica--either on a fiber tip or bulk substrates-- was implemented, characterized, and optimized to fabricate concave micromirror templates

Brain tumors or brain cancer is a disease than affects people of all ages. The median age of a person living with a brain tumor is 60 years, it is however a disease that affects children and young adults in high grade. Brain cancer is the second most common type of cancer among children and is also the most common cause of cancer related death among this group. To ensure that the damages on the brain is as small as possible, it is important that a tumor can be diagnosed and removed as early as possible. Previous methods of diagnosis is based on biopsy where a part of the tumor is removed and e

We report the ¯rst detection of nanographite ribbons on a highly oriented pyrolytic graphite substrate by Raman spectroscopy. We found a way to di®erentiate the Raman signal of the ribbon from that of the substrate, the Raman signal of the ribbon having the same order of magnitude as the one of the substrate, despite the much smaller number of illuminated carbon atoms (»10¡3).

One of the most current and also most promising fields of research in solid state physics is that of nano-structured materials. In particular, there is a great interest in nanostructured semiconductors, thanks to the latest developments in preparation techniques. These techniques allow to prepare nano-sized semiconductors with excellent crystalline structure and most often also with epitaxially determined orientations with respect to a template. The interest in nano-structures is triggered by the discovery that their physical properties (electronic, optical, thermodynamical) are different fro

Different theoretical approaches have been presented in this thesis to study the Raman scattering effect. The first one is response theory applied up to third order of polarization, where the determination of α, β and γ is used to calculate linear Raman scattering (resonance Raman scattering (RRS) and normal Raman scattering (NRS)), hyper Raman scattering (HRS) and coherent anti-Stokes Raman scattering (CARS), respectively. The response theory refers to adiabatic time-dependent density functional theory in the complex domain with applications on RRS and NRS, and to a recently developed methodo

The use of range-gating to produce images of particular range bins is also important in minimizing the image degradation due to light that is scattered backward from aerosols, smoke, or water along the imaging path. For practical lidar systems that must be operated within sight of unprotected observers, eye safety is of the utmost importance.

Abstract:

Femtosekundenaufgelöste Ramanspektroskopie ist ein leistungsfähiges Werkzeug, um die Schwingungsentwicklung eines angeregten Chromophors in Echtzeit zu studieren. In dieser Arbeit wurde ein durchstimmbares Ramanspektrometer mit 10 cm-1 spektraler und 50--100 fs zeitlicher Auflösung entwickelt und für eine Anwendung auf flavinbasierte Photorezeptoren optimiert. Es wird der Einfluß der Resonanzbedingungen auf das transientes Ramanspektrum charakterisiert. Die Dynamik des angeregten Zustandes wird zuerst für den Modellphotoschalter Stilben untersucht, ausgehend sowohl vom cis-, als auch vom tran
